Steady states of a quasiperiodically driven integrable system

Sourav Nandy, Arnab Sen, Diptiman Sen

Driven many-body quantum systems where some parameter in the Hamiltonian is varied quasiperiodically in time may exhibit nonequilibrium steady states that are qualitatively differe…

Fibonacci steady states in a driven integrable quantum system

Somnath Maity, Utso Bhattacharya, Amit Dutta +1

We study an integrable system that is reducible to free fermions by a Jordan-Wigner transformation which is subjected to a Fibonacci driving protocol based on two non-commuting Ham…

Critical phase boundaries of static and periodically kicked long-range Kitaev chain

Utso Bhattacharya, Somnath Maity, Amit Dutta +1

We study the static and dynamical properties of a long-range Kitaev chain, i.e., a -wave superconducting chain in which the superconducting pairing decays algebraically as $1/l^…

Transport in a thin topological insulator with potential and magnetic barriers

Adithi Udupa, K. Sengupta, Diptiman Sen

We study transport across either a potential or a magnetic barrier which is placed on the top surface of a three-dimensional thin topological insulator (TI). For such thin TIs, the…

Quantized transport in topological insulator n-p-n junctions

Abhishek Banerjee, Ananthesh Sundaresh, Sangram Biswas +3

Electrical transport in three dimensional topological insulators(TIs) occurs through spin-momentum locked topological surface states that enclose an insulating bulk. In the presenc…
